The first match of the main draw began Sunday night with Ryan Harrison, of the U.S., defeating Alexandr Dolgopolov of Ukraine.

“I went out there I played great it's hard not to play well in front of a fun crowd. Everyone out there is behind me. I felt the energy and I was really exciting to get through,” said Harrison.

Harrison goes on to play David Ferrer, of Spain, on Tuesday.

“It's going to be a tough one but I'm looking forward to it,” said Harrison.

As for the top matches on Monday, “Marty Fish has been in the finals two times, he's playing, Martina Hingis, she just got into the hall of fame, she's coming back and playing doubles. She'll be out here on Monday afternoon,” tournament Media Director Pete Holtermann said.

Holtermann said Monday night will also be a treat for tennis fans, “Venus Williams the seven-time grand slam champion and then one of the favorite guys on tour James Blake (will be here). It's a great start to the tournament at the Western and Southern Open.”

If you’re looking for tickets, Holtermann said they’re selling at a record pace this year but they are still available for all of the sessions. Monday is also Military Appreciation Day where there will be discounted tickets for current and former military members.
